4. How to choose the suitable Pneumatic DTH hammer?
Hole Size:
Selecting the one whose outside diameter is closest to the hole
diameter will be in your best interest. As a result, there will be
less hole collapse and easier hole cleaning.
Air Consumption:
It is important to take into account the compressed air usage when
using the pneumatic DTH hammer. Generally speaking, peak
performance necessitates lower pressure and more compressed gas
consumption as the hammer size increases. Please refer to the
attachment to ensure that each hammer is used with the appropriate
amount of pressure and compressed air.
Drill rig Capacity:
The drilling rig must supply more torque and promoting force to
accommodate the larger bit and hammer, but it must not go above the
drill's maximum load. As for the other questions about drill ability, please consult your
sales representative.
5. Is top hammer drilling vs down-the-hole drilling?
The primary difference between the top hammer and down-the-hole
drilling methods is where the hammer is attached. The hammer in the
industrial equipment makes contact with the bit during the
down-the-hole drilling method. The top hammer drilling method's
activity is concentrated at the very top of the drill string.
